Question
A ball of 1.00 kg initially travels at 20.0 m/s at 30.0° relative to the horizontal in the direction shown in the image. It impacts against a wall and bounces back at 17.0 m/s at 25.0° above the horizontal. Determine:
a. The magnitude of the impulse exerted by the surface on the ball.
b. The direction of the impulse exerted by the surface on the ball (in degrees counterclockwise from the positive X-axis).
c. If the duration of the contact is 1.20 ms, determine the magnitude of the average force in kilonewtons.
